Languages worth knowing

I did my last exam Friday.  I'm done school.  I've done mostly Java in school and this summer it's my mission to learn C++ by doing projects of my own.

Tell me why any other programming language is worth knowing.  I think Java and C++ fills just about all niches, and neither have forced indentation of code.

The right tool for the right job.
Learn C (not C++, C), forget Java, learn assembly, learn LISP, read K&R, read SICP.
Then you can learn/understand most languages

lastly but not related, how do you quote someone like >>6 did?
